10 best farm systems
1. Cardinals
Loaded big league club awaits Oscar Taveras, Shelby Miller and Trevor
Rosenthal.
2. Mariners
Their best prospects, even 2012 first-rounder Mike Zunino, have had Double-A
success.
3. Marlins
Blockbuster trade with Blue Jays propelled this system from middle of the
pack.
4. Rangers
No organization has more high-ceiling prospects, or one better than Jurickson
Profar.
5. Red Sox
Help is on the way with Xander Bogaerts, Jackie Bradley, Matt Barnes and
Allen Webster.
6. Rays
Dealing for Wil Myers and Jake Odorizzi helps to make up for recent
lackluster drafts.
7. Twins
The best collection of bats in the minors, led by Byron Buxton and Miguel
Sano.
8. Pirates
System isn't deep but has impressive trios of arms and bats that most can't
match.
9. Diamondbacks
No. 6 on my list before subtracting Trevor Bauer and adding Didi Gregorius.
10. Astros
Rebuilding will take time, but trades and 2012 draft are steps in the right
direction.
